如何在帶有 venv 的 Docker 映像中安裝 tensorflow？

Question

我有以下代碼...

FROM python:latest
ENV VIRTUAL_ENV "/venv"
RUN python -m venv $VIRTUAL_ENV
ENV PATH "$VIRTUAL_ENV/bin:$PATH"

# Python commands run inside the virtual environment
RUN /venv/bin/python3 -m pip install --upgrade pip
RUN /venv/bin/pip3 install tensorflow

但是當我跑步時，我得到...

ERROR: Could not find a version that satisfies the requirement tensorflow (from versions: none)
ERROR: No matching distribution found for tensorflow

我嘗試使用 tensorflow 圖像，例如...

FROM tensorflow/tensorflow:latest
ENV VIRTUAL_ENV "/venv"
RUN python -m venv $VIRTUAL_ENV
ENV PATH "$VIRTUAL_ENV/bin:$PATH"

# Python commands run inside the virtual environment
RUN /venv/bin/python3 -m pip install --upgrade pip

但后來我得到...

The virtual environment was not created successfully because ensurepip is not
available.  On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.

    apt-get install python3-venv

所以我改成

FROM tensorflow/tensorflow:latest
RUN apt-get install python3-venv -y
ENV VIRTUAL_ENV "/venv"
RUN python -m venv $VIRTUAL_ENV
ENV PATH "$VIRTUAL_ENV/bin:$PATH"

# Python commands run inside the virtual environment
RUN /venv/bin/python3 -m pip install --upgrade pip

但我得到...

E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/universe/p/python3.6/python3.6-venv_3.6.9-1~18.04ubuntu1.1_amd64.deb  404  Not Found [IP: 91.189.88.152 80]
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

我該如何處理？

每@drum評論這有效......

FROM tensorflow/tensorflow:latest
RUN apt-get update && apt-get upgrade -y
RUN apt-get install python3-venv -y
ENV VIRTUAL_ENV "/venv"
RUN python -m venv $VIRTUAL_ENV
ENV PATH "$VIRTUAL_ENV/bin:$PATH"

# Python commands run inside the virtual environment
RUN /venv/bin/python3 -m pip install --upgrade pip
